VAppncatimfi filed December 13, 1921. serial No. 522,110.

T all whom it may concern Be it known that I, MACE L. MASTERS, a.

citizen of the United States, and a resident of Mount Ulla, in thecounty of Rowan and State of North Carolina, have invented a new andImproved Safety Razor, of which the following is a full, clear, andexact description.

This invention relates to improvements inV safety razors, an object ofthe invention being to provide va safety razor in which'the handleforms, a continuation. of the guard and is .located in the .same planewith the.V

guard so thatthe razor may be handled with facility in shaving all partsofthe face.

A further [object is to provide a novel Afmeans'for supporting a blade,and to prof VFigure 4 is proved razor videV a razor which will be simpleand practical in construction, comprising a minimum number of parts, yetywhich will be strong, durable and efcient in use, neat and attractivein appearance,easy to clean, andl comparatively inexpensive tomanufacture. With these and other objects inview, the invention consists`in certain novel features of construction andV combinations andarrangements of parts as will be more fully hereinafter described andpointed out in the claims. Y

VIn the accompanying drawings: f Figure 1 is a top plan View of my im-Figure 2 is a view in longitudinal section therethrough on the line 2-2of Figure 1;

Figure 3 is a bottom plan view of thev razor; f Y

a view .in transverse Ysection on the line 4 4 of Figure 3; andv oFigure nis a lsimilar view illustrating a modication.

Referring in. detail tothe drawings, I have used the reference numeral 1to designate the handle of my improved razor. The handle, it will benoted, is in -skeleton form and includes a pair of laterally extendingfinger receiving portions such as 2. This handle may, if desired, bemade solid instead of in the skeleton form shown and may be decorated inany approved manner, as is customary in the art. A guard 3 forms acontinuation of the handle, the guard of course being appreciably widerthan the handle and being transverselybowed. Relatively narrow guardfingers 4 are provided at the edge of the guard and on the under face ofthe guard, a pair of longitudinally extending parallel ribs 5areintegral with the inner ends of the guard fingers. The guard isformed with three openings 6 in its. intermediate portion spaced kequaldistances apart. Y Y

ThroughoutV a portion of their lengtlrthe ribs 5 are formed with opposedgrooves such as 7 therein, and a wedge 8 is slidable in the grooves.This wedge is limited inone direction by engagement with the ends of thegrooves 7 and in the other direction by a stop Vfixed to the handleadjacent'the guard. The wedge member'8 is formed at its working end witha recess such as 10 providing a pair ofarms 11. The wedge is likewiseformed with'a slot 12 adapted to register with one Yof the openings 6 inthe guardand opposite its recessed end is provided with an angularthumb-receiving eX- tension 13 for operatin'g'the same.

I have indicated.y a conventional type of razor'blade 14. The bladeshown is flexible Y and is providedwith the usual three openings 14therein. A bowed backing plate 15 carries three studs such as 16 :whichareV accommodated in the openings in the blade. The central stud 16preferably includes a socket 17 and a headed screw 18 in the socket sothat this ystudcmay be' adjustable and the head movable for the purposeof exerting the desired tension on the blade.

- The operation of the device is as follows f The blade 141s mountedupon the backing plate 15, the studs 16 passing through the.

openings'14 in the blade. V'The studs 16 are Y then passed through theopenings 6 in the guard, oney of lthe studs( atV thesame timegextendingthrough the slot 12 in the wedge 8. It is Vmerely necessary to slide the`wedge forward so that thearms 11 straddle and enga-ge under the head ofthe screw 18, lockingthe bladeand backing plate infplace. The deviceisthenready for shaving. After use it may be disassembled by merelypulling the wedge member back and allowing the blade and backing plateto fall off. yIt should be noted that while I have shown the screw 18inconnection with the central stud 16 that I do not wish to be limitedto the use of this screw, since a solid stud having groovesV thereinwould serve substantially the same purpose. The screw merely permits asomewhat finer adjustment of tension on the blade.

In Figure 5, Ihave illustrated a modification wherein the wedge 8 isdone away with.

In this form of the device, 19 represents the guard,g20: the blade,andQl the backing plate. Instead of using the Wedge member, a centralthreaded stud or post 22 is provided on the backing plate Whichpassesthrough the aligned openings in the blade,

.n myself at liberty to, make such changes andA alterations as 'fairlyfall v vithin the spirit and scopeof the appended claims.
